# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, gender identity and expression, level of experience,
nationality, personal appearance, race, religion, or sexual identity and
orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at [mvvmcross@gmail.com](mailto:mvvmcross@gmail). All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
available at [http://contributor-covenant.org/version/1/4][version]

# PhotoView
PhotoView aims to help produce an easily usable implementation of a zooming Android ImageView.
[](https://jitpack.io/#chrisbanes/PhotoView)
[
## Dependency
Add this in your root `build.gradle` file (**not** your module `build.gradle` file):
```gradle
allprojects {
repositories {
maven { url "https://www.jitpack.io" }
}
}
buildscript {
repositories {
maven { url "https://www.jitpack.io" }
}
}
```
Then, add the library to your module `build.gradle`
```gradle
dependencies {
implementation 'com.github.chrisbanes:PhotoView:latest.release.here'
}
```
## Features
- Out of the box zooming, using multi-touch and double-tap.
- Scrolling, with smooth scrolling fling.
- Works perfectly when used in a scrolling parent (such as ViewPager).
- Allows the application to be notified when the displayed Matrix has changed. Useful for when you need to update your UI based on the current zoom/scroll position.
- Allows the application to be notified when the user taps on the Photo.
## Usage
There is a [sample](https://github.com/chrisbanes/PhotoView/tree/master/sample) provided which shows how to use the library in a more advanced way, but for completeness, here is all that is required to get PhotoView working:
```xml
<com.github.chrisbanes.photoview.PhotoView
android:id="@+id/photo_view"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
```
```java
PhotoView photoView = (PhotoView) findViewById(R.id.photo_view);
photoView.setImageResource(R.drawable.image);
```
That's it!
## Issues With ViewGroups
There are some ViewGroups (ones that utilize onInterceptTouchEvent) that throw exceptions when a PhotoView is placed within them, most notably [ViewPager](http://developer.android.com/reference/android/support/v4/view/ViewPager.html) and [DrawerLayout](https://developer.android.com/reference/android/support/v4/widget/DrawerLayout.html). This is a framework issue that has not been resolved. In order to prevent this exception (which typically occurs when you zoom out), take a look at [HackyDrawerLayout](https://github.com/chrisbanes/PhotoView/blob/master/sample/src/main/java/com/github/chrisbanes/photoview/sample/HackyDrawerLayout.java) and you can see the solution is to simply catch the exception. Any ViewGroup which uses onInterceptTouchEvent will also need to be extended and exceptions caught. Use the [HackyDrawerLayout](https://github.com/chrisbanes/PhotoView/blob/master/sample/src/main/java/com/github/chrisbanes/photoview/sample/HackyDrawerLayout.java) as a template of how to do so. The basic implementation is:
```java
public class HackyProblematicViewGroup extends ProblematicViewGroup {
public HackyProblematicViewGroup(Context context) {
super(context);
}
@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
try {
return super.onInterceptTouchEvent(ev);
} catch (IllegalArgumentException e) {
//uncomment if you really want to see these errors
//e.printStackTrace();
return false;
}
}
}
```
## Usage with Fresco
Due to the complex nature of Fresco, this library does not currently support Fresco. See [this project](https://github.com/ongakuer/PhotoDraweeView) as an alternative solution.
## Subsampling Support
This library aims to keep the zooming implementation simple. If you are looking for an implementation that supports subsampling, check out [this project](https://github.com/davemorrissey/subsampling-scale-image-view)
